In the if–else statement, if the expression/condition is true, the body of the if statement is

executed; otherwise, the body of the else statement is executed. The else keyword is used

when the expression is not true. The format/syntax of

tain statement/statements. When the expression is true,

the if block is executed, otherwise, the else block

is executed.
